Is there anyone who has tried this electronic flea collar :?: Or perhaps the plug in device :?: I am very interested in them but I bought one here (in Australia) and it was absolutely useless. Love to hear from anyone.

I wish I could help you but I've only seen a couple electronic devices for fleas and have no idea if they are useful or not. I swear by spot-on treatments (only certain brands--some can be harmful)

I once saw a device that was like a bug zapper. At night the fleas are supposed to be attracted to this light and go to it only to land in a tray of water (I think that's how it works). I'm not certain how effective it is.

Maybe the collar you are using is one of those items where you are supposed to use with something else. Like I know that feeding animals Brewers yeast (with garlic) is supposed to help repel fleas but I would never say that is a foolproof method and will cure a problem.
